The last two examples of the String/ String Format section are displayed incorrectly before you select to run the example. This is how they are displayed:
quantity = 3
itemno = 567
price = 49.95
myorder = "I want {} pieces of item {} for {} dollars." print(str.format(quantity, itemno, price))
quantity = 3
itemno = 567
price = 49.95
myorder = "I want to pay {2} dollars for {0} pieces of item {1}." print(str.format(quantity, itemno, price))
This is how they should be displayed:
quantity = 3
itemno = 567
price = 49.95
myorder = "I want {} pieces of item {} for {} dollars." print(myorder.format(quantity, itemno, price))
quantity = 3
itemno = 567
price = 49.95
myorder = "I want to pay {2} dollars for {0} pieces of item {1}." print(myorder.format(quantity, itemno, price))
